I can confirm that Bell indeed do not block IP protocol 41. Fantastic. I can also confirm that Bell's residential fibre service will transport an IPV6 tunnel successfully (which uses IP protocol 41). However, to succeed I had to use a separate router to connect using ppoe. Nothing I did would make it work if I used only the GigaHub. Now I have the GigaHub handling most of the ordinary traffic in my house (for my family members who don't care about my IPV6 travails) and a separate router, running OpenWRT, connected via ppeo that is successfully running the IPV6-over-IPV4 tunnel. My tunnelled IPV6 connection passes everything (except the hostname test, which is ok) on ipv6-test.com.
p.s. If you're wondering why IPV6 is important to me, it's because I have to test software that requires IPV6 connectivity. It's not optional for me. For most ordinary users it's totally irrelevant. For me it was a must have.
